Figure 5. — The winch, showing the plumber's cross and axle delivery and the power drive for the drum. 



The plumber's cross (fig. 6) is the upper 

 hose-cable terminal assembly where electrical 

 and support elements are separated from the 

 water. The hose is secured to a close nipple 

 in one horizontal opening of the cross with a 

 standard hose coupling, while the cable is 

 shackled to a ring welded to a pipe plug in the 

 opposite opening. A close nipple in the bottom 

 opening extends through a hole in the surface 

 of the drum. A 2-inch to 1 1/2-inch bell 

 reducer tightened on the nipple against a 

 broad washer facing the underside of the 

 drum surface holds the plumber's cross rigidly 

 in place. A 1 1/2-inch pipe extends from the 

 reducer to a union projecting from an opening 

 in the axle of the drum. The end plate of the 

 drum is set back 6 inches from the edge of the 

 cylinder so that the reducer and connecting 

 pipe are on the outside. The axle is plugged 



immediately behind the point where the radial 

 pipe joins it so that water flowing from the 

 plumber's cross is forced towards the outer 

 end of the axle. A right- angle 1 1/2- inch 

 swivel coupling turned onto the end of the axle 

 allows the axle to rotate without turning the 

 pipe screwed into the other opening of the 

 swivel coupling. The hose leading to the 

 filtering unit is clampled to this pipe. 



The powerline, which passes out of the 

 plumber's cross through a packing gland and 

 stuffing box in the top opening, is connected 

 with a watertight electrical coupling to another 

 line that is bent sharply towards the axle and 

 secured to the radial pipe between the bell 

 reducer and the axle. Free cable beyond this 

 point is spooled onto the axle as the drum is 

 rotated to let the hose out, and reeled off
